PT6324
VFD Driver/Controller IC
DESCRIPTION
PT6324 is a Vacuum Fluorescent Display (VFD)
Controller driven on a 1/8 to 1/16 duty factor housed in
52-pin plastic QFP/LQFP. 24 segment output lines, 16
grid output lines, one display memory, control circuit,
key scan circuit are all incorporated into a single chip
to build a highly reliable peripheral device for a single
chip micro computer. Serial data is fed to PT6324 via a
three-line serial interface.
